Find its shear deformation taking it to have the shear

Question

Please determine the solution of the given Problem

Problem-A disk between vertebrae in the spine is subjected to a shearing force of 640 N.

Part 1- Find its shear deformation taking it to have the shear modulus of 1 x 10⁹ N/m². The disk is equivalent to a solid cylinder 0.700 cm high and 3.70 cm in diameter.

I want help to evaluate the shear deformation taking of disk.
